Benefits of technology

"The invention is a container with a cap that can be opened and closed. The cap has inwardly projecting members that fit into recesses on the container body's lip to secure the cap. The cap can be rotated to tighten or loosen the fit. The design combines the aesthetics of a crown cap with the convenience of a screw cap, and the cap is lighter than a conventional plastics screw cap because it uses less material."

Problems solved by technology

Whilst very successful, this form of closure has the disadvantage that it requires a tool, e.g. a bottle opener, to prize the cap off the bottle.
In many cases, these caps can be installed by pressing onto the bottle (rather than being screwed on) but their removal requires the cap to be unscrewed, often requiring rotation of the cap through 360 degrees or more.

second embodiment

[0053]FIGS. 4-8 illustrate a container according to the invention. This is similar to the container shown in FIGS. 1-3 but also has a first type of tamper evident feature. Parts of the container of FIGS. 4-8 which correspond to those of the container of FIGS. 1-3 are given the same reference numeral but increased by 10.

[0054]The cap 12 is similar to the cap 2 but has a tamper band 10 depending from the skirt portion 17 thereof. The tamper band 10 is connected to the skirt portion 17 by a plurality (sixteen in the illustrated example) of small, friable bridges 10A and a plurality (four in the illustrated example) of tether bands 10B. A plurality (four in the illustrated example) of projections 10C project radially inwards from the inner surface of the tamper band 10.

first embodiment

[0055]When the cap 12 is pressed onto the container body 11 in the direction D1 shown in FIG. 5, the skirt portion 17 is flexed into a substantially polygonal shape as the members 18 ride over the lip 14 until they engage recesses 15 as in the In addition, the projections 10C ride over the lip 14 when the cap 12 is pressed onto the container body 11 and, once the cap 12 has been rotated in the direction D2 shown in FIG. 5, the projections 10C are located beneath lower surfaces 14D of the portions 14C of the lip 14 between the recesses 15.

[0056]The lower surfaces 14D of the lip 14 are inclined in the circumferential direction so that when the cap 12 is rotated in the direction D3 (the loosening direction) as shown in FIG. 6, the projections 10C are driven downwards as illustrated by arrow D4 in FIG. 6. As the remainder of the cap 12 is unable to move downwards (as it is engaged on the upper surface of the lip 14), this causes rupture of the friable bridges 10A (as shown in FIGS. 6 a...

third embodiment

[0058]FIGS. 9-13 illustrate a container according to the invention. This is similar to the container shown in FIGS. 1-3 but also has a second type of tamper evident feature. Parts of the container of FIGS. 7-13 which correspond to those of the containers of FIG. 1-3 are given the same reference numeral but increased by 20.

[0059]The cap 22 is similar to the cap 2 but has a tamper band 20 depending from the skirt portion 27 thereof. The tamper band 20 is connected to the skirt portion 27 by a plurality (about twenty four in the illustrated example) of small, friable bridges 20A and a single tether band 20B. A lower portion 20D of the tamper band is folded inwards (as illustrated by arrow B in FIG. 10) so that the upwardly facing edge 20E thereof projects radially inwards from the inner surface of the tamper band 20 around the entire internal circumference thereof.

[0060]When the cap 22 is pressed onto the container body 21 in the direction D1 shown in FIG. 11, the skirt portion 27 is f...

Abstract

A container comprising a container body (1) with an opening (3) defining an axis (A) passing therethrough and a cap (2) having an upper portion (6) and a skirt portion (7) for closing the opening, the container body (1) having an outwardly projecting lip (4) around the opening (3), the cap having spaced apart inwardly projecting members (8) round an inner circumference of the skirt portion (7) and the lip (4) having recesses (5) in a lower part thereof for receiving the members (8) when the cap (2) is press fitted to the container (1), the cap (2) being arranged so that its circumference is distorted into a substantially polygonal shape as portions of the cap carrying the members (8) are flexed outwards when the cap (2) is pressed over the lip (4) until the members (8) snap fit into respective recesses (5) in the lip (4), the members (8) and recesses (5) being shaped such that subsequent rotation of the cap (2) relative to the container body (1) tightens the cap (2) against the lip (4). Various tamper evident bands connected to the skirt portion (7) by friable bridges (10A, 20A, 30A, 40A) and / or tether bands (10B, 20B, 30B) are also described.

Description

TECHNICAL FIELD[0001]The present invention relates to containers, and particularly to containers for supplying beverages to consumers. The invention has particular utility for the storage and supply of carbonated and other sparkling drinks, but is also suitable for use with non-carbonated drinks and other types of beverage or other materials.BACKGROUND ART[0002]A well known drink container comprises a glass bottle with a crown cap formed of metal. The cap is pressed over a lip around the opening of the bottle and held in place by being crimped beneath the lip. Whilst very successful, this form of closure has the disadvantage that it requires a tool, e.g. a bottle opener, to prize the cap off the bottle.[0003]Other well know forms of container comprise a plastic bottle with a plastic screw cap. In many cases, these caps can be installed by pressing onto the bottle (rather than being screwed on) but their removal requires the cap to be unscrewed, often requiring rotation of the cap th...
